This appeared when Windows update ran just now
'Windows 11, version 25H2'

I'm already running 25H2. It just appeared in the update list and did a quick install, no restart.

I didn't have it, maybe because my 25H2 was installed as a repair update. I wasn't able to install 25H2 the normal way during those hard times for updates. Anyway, the regular monthly update is expected tomorrow, I hope for the best.

Update: fixed. I know what the issue was.

I set up a local Admin account, the first time I used it I didn't select to include Optional data in the telemetry.
As I run Release Preview it got confused as it showed I wasn't in the insider program.
Selecting the optional telemetry again fixed that and it didn't try downloading anything this time
